We’ve talked before here at BoingBoing about how “Colony Collapse Disorder” is probably more than one thing, with more than one cause. Another important detail to keep in mind as you read media reports on bee deaths — the collection of symptoms that we call Colony Collapse Disorder is also probably a lot older than you think. In a guest post at Bug Girl’s blog, bee expert Doug Yanega explains that CCD didn’t start in 2006. In fact, periods of mass bee die-offs with the same collection of symptoms have been recorded at least 18 times, dating back to 1869.
